Gig Bag Cleaner

My gig bag for my upright is looking a bit dusty and was hoping to find a good cleaner to spruce it up. Is there something out there for this? I've used a lint cleaner but it doesn't do a good enough job.

I feel like a shill because this is my second plug this month, but I have no commercial afflilations.

Look at NikWax products. They can be found on-line or at places like REI. They have cleaning products and waterproofing products. I was mine in tech wash and then either wash it again in a proofing product or spray it with their tent water proofing. A great way to clean it and get some weather resistance heading into winter.
